Procedure
0.39 g of 1-(3-(2-(1-benzothiophene-5-yl)ethoxy)propyl)-N,N-dimethyl-3-pyrrolidinamine was dissolved in 4.0 ml of ethyl acetate. Thereafter, 0.80 ml of an ethyl acetate solution containing 3.25 mol/l dry hydrogen chloride was added to the obtained solution, and the mixture was stirred at a room temperature for 1 hour and then at 5° C. for 1 hour. Thereafter, precipitated crystals were collected by filtration. The crystals were washed with ethyl acetate and then dried, so as to obtain 0.32 g of an achromatic crystal, 1-(3-(2-(1-benzothiophene-5-yl)ethoxy)propyl)-N,N-dimethyl-3-pyrrolidinamine dihydrochloride.
